Fallon began working for the Mitchell brothers at their San Francisco strip club, the O'Farrell Theatre, in the mid-1980s. She would perform a stage act where she would seemingly orgasm and squirt fluid from her vagina. This earned her the nickname "Squirt." She is mentioned in David McCumber's book about the Mitchell brothers, X-Rated, which claims that she actually would use water and hold it in her vagina with her strong PC muscles.

Fallon first retired from porn in the mid-1990s after appearing in more than 200 films. She came back to the industry in 2002, featured in a series of "mature woman" videos, despite the fact she was only in her mid-30s at the time.

Compiling an accurate filmography of her adult film career is made difficult by the wide variety of stage names she has used.

She also appeared in two films while pregnant, performing sex scenes in both Ready to Drop 2[5] and Fallon's Follies.
